HIDE-SECURING APPARATUS..

SPECIFICATION forming part of Letters Patent No. 707,559, dated August 26, 1902.

` Application filed December 301 1901. Serial No. 87,701. (No model.)

T @ZZ whom, it may concern:

Be it known that I, HUGH Y. B. DUFF, a citizen of the United States, residing at Chesf wick, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Hide-Securing Apparatus, of whichimprovement the following is a and the surface thereof treated to several.

. coats of the enamelingor japanning medium,

` gaging position.

each of said' coats being separately dried in a kiln at a temperature approximating 150o Fahrenheit. The above-mentioned frames being of wood and subjected to almost constant heat become so warped and out of order in a short time as to become practically useless, necessitating being replaced by new frames, which is not only a constant source of annoyance, but increases the cost of leather production. Furthermore, it is customary in the process of manufacturing said enameled or japanned leathers to perforate the edges thereof to string the same to the frame, which edges, being thus damaged, decrease the profits. v

The object of my invention is to provide a frame which will be practically indestructible and means therewith for securing the hide in position without damage thereto, together with certain details of construction and combination of parts, as will be fully described hereinafter.

In the accompanying drawings, Figure lis a plan View of my apparatus, showing the application of a hide thereto. Fig. 2 is an enlarged perspective view of a portion of the frame. Fig. 8 is a'perspective view of one of the clips as employed to secure the hide, said clip being shown in its open .or non-en- Fig. 4 is a side Aview of the same, showing the clip closed and engaging the hide.

To put my invention into practice, I provide a metal channel-bar l of suitable length and depth and bend the same into the form of a rectangle, the corners of which I brace by means of diagonally-disposed bars 4, at-

5. Along the flanged edges of said frame are formed aseries of tongues 3, arranged in pairs and disposed in opposite directions and presenting inclined engaging edges 3 at their rear or integral ends.

To engage the hide and connect the same to the frame, I employ a plurality of springclips 2O andconnect the saine to the tongues .of the frame by means of cords 16, passed thereabout to engage the edges 3. I have shown a form of spring-clip which is admirably adapted for this particular apparatus, consisting of a U-shaped frame 7, having an outwardly-extending eye portion 8 to connect the cord therewith, said frame having an opening 13 inits upper portion, at the forward end of which are formed the bearings 9. Fitted into this frame and secured to the lower portion thereof by the conical-headed rivets l5 vis flat spring 14:, carrying near its upper outer end the spurs 15'. A lever Il, having a right-angular extension' 12 upon its forward end to engage said spring, is mounted in the bearings of said frame by means of a small shaft '9.

In operation the clip-levers are pulled up, as illustrated at Fig. 3, and slipped over the edges of the hide 6 at the most convenient points, after which the lever is forced. down to cause the ends of-the spring to engage the hide, as illustrated at Fig. 4.. The ends of the cords 16 arethen passed around the frametongues and drawn taut to stretch the hide and cause said cords to be engaged in the corners 3, which corners will owing to their inclination and square edges eectually prevent said cords becoming slack when once in position. A coat of enameling or japanning medium is then applied to the surface of the leather and the apparatus placed in the kiln to dry, after whicl1,if'the hide should expand, the slack occasioned thereby may easilyy these frame-tongues and cords the most minute adjustment is attained, and no knots IOO y are required on the cords to insure a grip,-

thereby saving time and labor. Furthermore,

the frame is capable of maintaining its use-' invention, what I claim as'new, and desire to secure by Letters Patent, is

l l'. An apparatus for the purpose set forth, comprising in combination a metal frame, a plurality of hide-engaging clips, having fiexible extensions, and means for adj ustably connecting said clip extensions with said frame. 2. An apparatus for the purpose set forth,

comprising in combination a metal frame, a plurality of spring hide-engaging clips provided with fiexible extensions, and' means carried by said frame to adj ustably engage said clip extensions.

3. An apparatus for the purpose set forth, comprising in combination a metal frame having fasteners on one side thereof, and hideengaging clips provided With flexible eXtensions to adjustably engage with said framefasteners.

4. An apparatus for the purpose set forth, comprising in combination a metal frame having a series' of fasteners on one side thereof eachy consisting of two oppositely-inclined tongues, and a plurality of spring hide-engaging clips having flexible extensions to engage said frame-tongues. In testimony whereof` I have hereunto signed my name in the presence of two subscribing Witnesses. HUGH Y. B. DUFF. In presence of- E. C. OHAMBERLAIN, JOHN T. DUFF.
